BURNER.

SPECIFICATION forming part of Letters Patent No. 427,383, dated May 6, 1890.

Application filed May 3, 1889. Serial No. 309,484. (No model.)

To all whom, it may concern.-

Be it known thatI, THOMAS \VALL, of Brooklyn, in the county of Kings and State of New York, have invented a new and Improved Lamp-Burner, of which the following is a full, clear, and exact description.

The object of my invention is to provide a burner in which the parts are firmly secured together without the use of solder and at a minimum cost.

The invention consists in the particular construction and arrangement of parts, as hereinafterfully described, and pointed out in the claim.

In coustructin g the burner I employ a novel die and plunger, which will be hereinafter described, but to which I make no claim in this application.

Reference is to be'had to the accompanying drawings, forming a part of this specification, in which similar figures and letters of refereuce indicate corresponding parts in all the views.

Figure 1 is a central sectional elevation of the die and plunger employed in the construction of my improved lamp-burn er, the burner being represented in an inverted position and in central vertical section. Fig. 2 is an inverted plan view of the plunger. Fig. 3 is a sectional elevation of the plunger on line a: 00 of Fig. 2. Fig. 4 is a plan view of the die. Fig. 5 is a sectional elevation of the die on the line 10 w in Fig. 4. Fig. 6 is a sectional View of the plunger, the View being taken on line 1 y of Fig. 2. Fig. 7 is a detail sectional view of the die, and Fig. 8 is a sectional plan view of the burner on the line z z in Fig. 1.

In the drawings, 1.0 represents a die, in" which there are pivotally mounted tongues 11, said tongues being housed within a recess a, of proper form to receive the upper port-ion of the wick-tube of the burner. The approach- I employ a head-block 15, in which there is mounted a movable plunger 16, said plunger being normally held in the position in which it is shown in Figs. 3 and 6 by springs 17, which bear against the upper outer edges of tongues 18, that are pivotally connected to the plunger 16. To the head-block 15, I connect a downwai'dly-extending rigid tongue 20, which is formed with two inclined-faced projections b and with inclined bearing-faces c at its lower end, the inclined faces I) being arranged to bear against the inner approaching faces of the tongues 18 when the plunger is forced upward against the tension of its springs 17. The plunger is apertured to re ceive the lower end of the wick-tube of the burn er, andit'is Within the aperture so form ed in the plunger that the tongues 18 are mounted. The upper portion 30 of the burner forming the subject-matter of this application is formed with two or more apertures cl, and preferably with three of such apertures, and the lower portion 31 is formed with upwardlyextending tongues 6, arranged to register with the apertures 61, the upper and lower portions of the burner and the wick-tube 32 being formed in the ordinary manner.

In associating the three portions of the burner above referred to I place. the upper portion 30 upon the die 10, and I pass the wick-tube 32 downward within the die-recess a,'the tongues 11, being within the wick-tube. The lower portion of the burner is then placed in position upon the upper portion, so that its tongues 6 will enter the apertures d. When the parts are adjusted as above described, the

lower end of the wick-tube Will rest within the recess in the plunger 16, the tongues 18 hearing against the wick-tube just above the bottom of the lower section of the burner. Then, if the head-block 15 be depressed, the tongues 11 will be forced outward above the bottom plate of the main section of the plunger and the tongues 18 will be forced outward, so as to form projections that Will be below the bottom of the lower section of the burner, said projections formed by the tongues 11 and 18 being shown at f and g, respectively. In this way I securely lock the several portions of the burner together and obviate the use of solder, said solder under certain eircumtion 30, and the wick-tube 32, provided with stances being extremelyundesirable, owingto the projections g near its lower end and bethe fact that it Will at times melt. low the lower end of thelower section 31, and Having thus described my invention, I With the projections f about its center and 5 claim as new and desire to secure by Letters above the bottom plate of the upper section, I 5

Patent as specified.

The herein-described burner, consisting of THOMAS \VALL. the section 30 provided With the apertures Witnesses: d, the lower section 31, provided with the ROBERT SEALY,

1o tongues e, fitting in the apertures of the sec- JOHN M. MCCORMICK.
